Maybe the most impressive watch from Omega visually when you see it in person, the 125th Anniversary is just a monster of a watch. Bearing the Caliber 1041, this watch is in untouched condition with all its original parts and straight as an arrow when it comes to its overall condition. I believe the sides to have been brushed previously on the case but overall it is a very good example.
